Background technology
The title of submitting on December 20th, 2006 is the Peter M.Kazmaier of " the sense of touch security feature that is used for document authentication and signature authentication ", Hadi K.Mahabadi, Paul F.Smith, Chris A.Wagner, the common transfer of Gabriel Iftime and Tyler B.Norsten, common unsettled U.S. Patent application 11/613,759 (its full content mode is by reference included this paper in) have been described a kind of system and method that generates the authentication sign in the following manner on recording medium in embodiments, are about to marking materials and deposit on the medium in the image-region to generate the marking materials image and to generate the marking materials authentication image.The additional identification material of scheduled volume is further deposited on the medium in described authentication image zone to increase the amount of marking materials relevant in the authentication image zone with the marking materials authentication image.The fixing marking materials relevant with described authentication image zone is to identify by the authentication that touch perception arrives, but wherein relevant with described authentication sign fixing marking materials has the height with respect to the sense of touch of described dielectric surface.
United States Patent (USP) 6,644,763 have described a kind of method of using ink-jet technology to produce relief printing effect and special printing effect.Described method comprises the steps: photo curable photopolymer material deposited to and is selected to produce on the zone of described printing effect, and solidifies this zone.The amount of material to be deposited is relative with zone that is selected to produce described printing effect and described elevated regions, and to deposit the height of medium of photopolymer material thereon corresponding.Referring to its summary.
United States Patent (USP) 5,627,578 described a kind of by the printing ink sprayed deposit is carried out the literal of relief or the method and apparatus of graphic printing to the material of undertaking the printing of.Subsequently with the thermal sensitivity powder dispense on it, this powder only adheres on the wet ink, is heated to the fixed temperature of described powder then, thereby forms the literal or the figure of projection.The portable ink-jet printer of foaming inkjet type (being controlled with graphics software by personal computer) of standard provides necessary contactless ink deposition.Distribution drum to ink-jet printer provides contactless drying oil ink preparation (can have two or more different colors if necessary), and being used in to become on the part of the figure of relief form or printed matter.The distributor of thermal sensitivity powder and heater block are connected to the output of ink-jet printer or integrated with it, to finish described relief print procedure.By using drying oil ink and the nondrying oil China ink that distributes respectively, relief is printed and the printing of non-relief also is feasible.Referring to its summary.
Ink jet printing device is well known in the art.For example, ink jet printing device is divided into two types usually: continuous flow type and drop on demand ink jet formula.In the continuous flow type ink-jet system, under pressure, penetrate printing ink in the Continuous Flow mode by at least one spray orifice or nozzle.Described stream is disturbed, and causes it being separated into droplet apart from the fixing distance of described spray orifice.At the spaced point place, make described droplet charged according to digital data signal, and make it pass electrostatic field, described electrostatic field can be adjusted the track of each droplet so that the ad-hoc location on its directive recycle tank or the directive recording medium.In drop-on-demand systems, droplet is transmitted directly to certain position on the recording medium from spray orifice according to digital data signal.Only prepare droplet is placed on the described recording medium, otherwise can not form or launch this droplet.Generally speaking, there are three class drop on demand ink jet formula ink-jet systems.One class drop-on-demand systems is to have printing ink to fill raceway groove or the passage piezoelectric device as its primary clustering, and the end that described printing ink is filled raceway groove or passage has a nozzle, and has a PZT (piezoelectric transducer) near the other end to produce pressure pulse.Another kind of drop-on-demand systems is called as the sound wave ink print.Known, acoustic beam can apply radiation pressure to the object that it collides.Therefore, when acoustic beam collides the free surface (being liquid/air interface) of liquid cell from the below, its radiation pressure that is applied on the described pool surface can reach sufficiently high level to discharge single liquid droplet from this pond, even there is capillary restraint.With sound beam focusing on the surface in described pond or neighbouringly strengthen the radiation pressure that it is applied under the input power of specified rate.Another kind of drop-on-demand systems is called as hot ink-jet or bubble formula ink jet printer, and produces the high speed droplet.The primary clustering of this class drop-on-demand systems is that printing ink is filled raceway groove, and the end that described printing ink is filled raceway groove has a nozzle, and a heat production resistance is arranged near this nozzle.Represent near the resistive layer of each oil ink passage of print signal spray orifice or nozzle of digital information and produce a current impulse, cause almost evaporation immediately and produce bubble of the most contiguous ink carrier (being generally water).Along with the expansion of this bubble, the printing ink of spray orifice is extruded to advance the droplet form.
In a kind of piezoelectric ink jet equipment of typical style, apply image by the printing ink that in the material of undertaking the printing of (accepting parts or intermediate transfer element as image) 4 to 18 rotation (incremental motion) processes, sprays suitable color with respect to ink gun.That is, printhead all has a little translation with respect to stock matter between each rotation.This method has been simplified the printhead style, and good droplet location has been guaranteed in described little motion.Under the operating temperature of described ink-jet printer, the droplet of liquid ink is ejected from described PRN device.When described droplet and record used the surface of the material of undertaking the printing of to contact, they solidify to form the predetermined pattern that is made of the droplets of ink of solidifying fast.
Inkjet printing methods can adopt when room temperature to be solid and to be the printing ink of liquid when heating up.This class printing ink can be called as solid ink, heat fusing printing ink, phase change ink etc.For example, U.S. Patent No. 4,490,731 (its disclosure mode is by reference all included this paper in) disclose a kind of dispense solid printing ink that is used for to print to such as the device on the materials of undertaking the printing of such as paper.In the thermal inkjet-printing method that adopts heat fusing printing ink, described solid ink melted with the heater in the printing equipment and as liquid with to conventional thermal inkjet-printing in similar mode use (injection).In case when contacting with the material of undertaking the printing of of printing usefulness, described molten ink is promptly solidified fast, make colorant can stay on the surface of the described material of undertaking the printing of in a large number, rather than, take this to make that print density is higher than the print density that common use liquid ink obtains because of capillarity is brought in the described material of undertaking the printing of (for example paper).Therefore, the advantage of phase change ink has been to eliminate printing ink loss possible when handling, multilevel print density and quality, minimal curl or deformation in the inkjet printing, and make the danger that can not occur nozzle blockage when not printing for a long time, even do not use to add cap to nozzle.
The purposes that ink-jet printer is used to form the relief print image also is known, for example, and as above-mentioned United States Patent (USP) 6,644,763 and 5,627, described in 578.Yet these printers that are used to form the relief image are generally and only design and be used for the relief print application as forming the special purpose machinery of braille image etc.When the user only needs to print certain a when part of finishing print job with relief, have two PRN devices and wherein one be specifically designed to and carry out the relief print job, be the comparison costliness for the user.
Two kinds of technology that are used to print braille and relief literal of main existence: die mould (embossing) and hotness paper expansion (thermal paper expansion).As mentioned above, these equipment are specifically designed to the relief printing.Be starved of the printer that a kind of can normally printing simultaneously (non-relief is printed or " routine " printed) and relief and braille are printed.For example, government and legal requiremnt will greatly have benefited from this equipment for the dysopia crowd provides the large corporation of braille printing product.Government and educational institution are starved of the double mode printer that can print conventional printed matter and braille and cameo printing product.At present, there is a kind of printer that can utilize the physics embossing machine to print braille and normal text simultaneously on the market.This equipment produces by a line of forming, and it has relatively poor image resolution ratio and can not print figure and the image with change in elevation.When needs, it is hand-made that the height of variation such as figure etc. typically use thermoforming process.In addition, embossing machine is the great machine of noise, needs soundproof room.Thermal expansion paper is also very very expensive, every paper more than 1.00 dollars usually, and it needs a complexity and two step print procedures slowly, and is subject to the plastic-like special use material of undertaking the printing of.
The relief text printout that is combined with braille letters that also needs prior art to realize.For example, the braille expression formula of mathematics and chemical equation and finance formula is extremely huge and loaded down with trivial details.Need a kind of method of space economy, the relief letter and number can be used for these application.
Usually, phase change ink (being called as " heat fusing printing ink " sometimes) is solid phase when room temperature, but is liquid phase when the operating temperature of the rising of ink jet printing device.Under the operating temperature of described ink-jet printer, the droplet of liquid ink ejects from described PRN device, and directly or via the thermal transfer ribbon of centre or drum and record usefulness undertake the printing of the surface of material when contacting when described droplet, they solidify to form the predetermined pattern that is made of the solidified oil ink droplet fast.Phase change ink also has been used in other printing techniques, for example intaglio plate is printed, and for example United States Patent (USP) 5,496,879 and open text DE 4205636AL of Deutsche Bundespatent and DE 4205713AL in disclosed, the disclosure of the described patent of each piece all by reference modes include this paper in.
The phase change ink that is used for colour print generally includes the phase change ink carrier composition that combines with phase change ink compatibility colorant.In a specific embodiment,, ink-vehicle compositions can form a series of coloured phase change inks by being combined with compatibility subtractive primaries colorant.The phase change ink of described subtractive primaries can comprise that four kinds are formed dyestuffs or pigment, i.e. blue-green, reddish violet, yellow and black, but described printing ink is not limited to this four kinds of colors.The printing ink of these subtractive primaries can form by using independent a kind of dyestuff or pigment, dye mixture and colorant mixture or their combination.For example, reddish violet can obtain by the mixture that uses the solvent red dyestuff, perhaps synthetic black can the acquisition by mixing several dyestuffs.United States Patent (USP) 4,889,560,4,889,761 and 5,372,852 (all whole modes by reference of its disclosure are included this paper in) have instructed the subtractive primaries colorant that is adopted can comprise the dyestuff of following color index (C.I.) kind: the acidity of solvent dye, disperse dyes, modification and direct dyes and basic-dyeable fibre.Described colorant can also comprise pigment, and is disclosed in 335 as United States Patent (USP) 5,221, and the disclosure of described patent all by reference modes is included this paper in.United States Patent (USP) 5,621,022 (the whole modes by reference of the disclosure of described patent are included this paper in) discloses the concrete purposes of a class polymeric dye in phase change ink composition.
Phase change ink also has been used for the application such as postmark, industry sign and label.
Why phase change ink meets the needs of ink-jet printer, is because they can remain in solid state shape in room temperature in processes such as transportation, Long-term Storage.In addition, and because the relevant problem of the spray nozzle clogging that evaporation caused of liquid jetted ink is eliminated largely, so improved the reliability of inkjet printing.In addition, described therein ink droplet is applied directly to final record with in the phase change ink-jet printing machine on the material (for example paper, transparent material etc.) of undertaking the printing of, described droplet solidifies when contacting with the described material of undertaking the printing of immediately, is improved along described print media migration and net-point quality so that can prevent printing ink.
Radiation curable ink comprises particularly light trigger of at least a curable monomer, a kind of colorant and a kind of radioactivated initator usually, and the curable components that described initator can cause printing ink is the polymerisation of curable monomer particularly.
The United States Patent (USP) 7,279,587 of Peter G.Odell, Eniko Toma and Jennifer L.Belelie (the whole modes by reference of the disclosure of described patent are included this paper in) discloses the light-initiated compound that is used for curable phase change ink composition.In embodiments, a kind of compound with following formula is disclosed

Ink jet-print head 11 can be carried by the load bearing component (not shown) that holds that is fit to.In the normal image forming device, described ink jet-print head is installed to be fixing, perhaps be installed as at the most fixed distance apart from the print area surface, but can move the surface of crossing this print area vertically, for example mobile on the direction of observing Fig. 1 toward and away from the observer.In the embodiment of this paper, the ultraviolet gelling agent printing ink of this paper is designed to directly using to paper printer (directto paper printer).
Yet, in the device of this paper embodiment, it is adjustable that ink jet-print head is installed as the distance (being also referred to as the height distance between described ink jet-print head and the described print area surface in this article) that makes between described ink jet-print head and the described print area surface.
In embodiments, making ink jet-print head be located at image accepts to undertake the printing of and forms the normal place of conventional height image on the material.For monochrome, conventional height image has about 5 μ m usually to about 15 μ m, the printing of for example about 10 μ m height, and therefore, for for example stacked polychrome in the full-color print image of part, it highly can be about 20 μ m to about 45 μ m.For this reason, described ink jet-print head can be positioned at apart from shower nozzle and will spray the about 80 μ m in print area surface of marking materials up to about 200 μ m, for example about 100 μ m places.
In embodiments, this " the conventional height and position " of described ink jet-print head will be represented first height distance between ink jet-print head and the print area surface, described first height distance can be the minimum constructive height distance, and wherein said printhead is positioned at immediate position, itself and described print area surface.
Though this primary importance of ink jet-print head is qualified for monochrome image or the multicolor image of printing conventional height, has produced difficulty when attempting to form the image with height of projection.For example, use for braille, the height of image should be at least about 200 μ m so that described image can easily be discovered and deciphering correctly by touching.If attempt by for example known technology (as ink jet-print head repeatedly by) make the height of image surpass 200 μ m, then ink jet-print head finally will contact and destroy the image of being printed.Therefore exist one to surpass the printing limitation in height that standard ink jet inks PRN device then can not be printed.Here it is, and why the standard ink jet inks printer can not be used to form the image with height of projection, and why the user has to buy the reason that is specifically designed to the independent PRN device that forms the image with height of projection.
Among the present invention, ink jet-print head is adjustable with respect to the distance on print area surface, so that make ink jet-print head be used for the conventional highly primary importance of printing and move to second height distance greater than described first height distance (be between ink jet-print head and the print area surface distance greater than described first height distance) from above-mentioned.Described second height distance is not fixed, and can change according to the needs of given printing.In addition, in print procedure, described second height distance can change as required itself.For example, when using ink jet-print head to set up image, may need height distance is adjusted to the second place from primary importance, when continuing to set up image, ink jet-print head is adjusted to the 3rd position that further increases apart from the distance on print area surface from the second place then, as required by that analogy to finish the foundation of image.
When setting up image, for example by make printhead repeatedly from parts of images by when comprising the relief image, each of image layer can have the printing height of about 4 μ m to about 12 μ m.Can select to carry out passing through or ink-jet of suitable number of times, have required total relief image of printing height so that can set up, for example at least about 80 μ m, 80 μ m are to about 600 μ m according to appointment, and perhaps about 300 μ m are to about 500 μ m.By this way, can reach the standard that sets by blind person and developing material for disabled persons center National Library (National Library For The Blind AndPhysically Handicapped Materials Development Center).Particularly, described standard is the site height: 0.020 inch (0.51mm); Site distance: 0.09 inch (2.29mm); Pitch character is from 0.240 inch (6.10mm); And line-spacing: 0.40 inch (10.16mm).
Ink gun can be supported monochromatic or full-color printing.In full-color printing, ink gun generally includes the different raceway grooves that are used to print different colours.As shown in Figure 2, ink gun can comprise four groups of different raceway grooves, for example distinguishes corresponding blue-green, reddish violet, yellow and black separately.In this class embodiment, printhead can either be printed full-color conventional height printed matter---this moment ink gun be set to and the print area surface between distance minimum, also can print and have printed matter arbitrary color combination, that have height of projection---the distance between this moment ink gun and the print area surface is greater than this minimum range.
Adjusting ink jet-print head, can use arbitrary suitable Height Adjustment mechanism with respect to aspect the height on print area surface.Described Height Adjustment mechanism can be associated with ink jet-print head or print area surface.Described Height Adjustment mechanism can comprise the route that can be used for moving or spur described band so that its mechanism of any type of ink jet-print head further away from each other, and for example therefore cylinder etc. probably has the Height Adjustment mechanism that is associated with the print area surface.
For ink jet-print head, can use any suitable Height Adjustment mechanism.For example, the support shell that ink jet-print head is installed can comprise driver (or mini drive), be used in the following manner height distance suitably being adjusted: for example reach suitable distance away from the print area surface by the printhead of drive installation on support, for example about 10 μ m are to about 1000 μ m, for example compare with the primary importance or the minimum position place of ink jet-print head, with the distance on print area surface about 10 μ m far away again to about 800 μ m.Described driver can be positioned at the site that ink jet-print head is installed on the support, so that fixture comprises the height distance adjusting device.
Other examples of Height Adjustment mechanism can comprise, for example ink jet-print head is installed on the fixture, described fixture can swing up and down around pivot, a for example rotatable shaft expansion bend (rotatable shaft retractor) that is fixedly connected to described fixture so that the rotation of pivot can drive ink gun near or away from the print area surface.Expansion bend also can be used for making described fixture to move toward and away from the print area surface linearly.Also can adopt any other method that the ink jet-print head fixed is moved toward and away from the print area surface, as biasing mechanism (biasing mechanism), for example spring, positive hydraulic pressure, positive air pressure, screw mechanism etc.
For the print area surface, can use any suitable Height Adjustment mechanism.Above pointed out exemplary belt Height Adjustment mechanism.
Described Height Adjustment mechanism can be by controller control, and described controller can be same controller with the controller of control ink jet-print head ink-jet.By this way, can in having the process of image of height of projection, printing suitably adjust the height distance of ink jet-print head as required apart from the print area surface.
